Description

Technical Field

[0001] This invention relates to the field of cotton seedling cultivation technology, specifically to a cotton seedling cultivation device for preventing diseases and pests. Background Technology

[0002] Cotton belongs to the genus *Gossypium* of the family Malvaceae. There are several varieties, including upland cotton, herbaceous cotton, and tree cotton. Cotton has a long growth cycle and requires more sunlight than other crops. It thrives in well-drained soils such as sandy loam, loam, and light clay. Its roots have a strong regenerative capacity, able to grow new roots after damage. Cotton is typically propagated by seeds, seedlings, or sowing.

[0003] Currently, existing cotton seedling cultivation devices designed for disease and pest control have the following shortcomings in use: Typically, after the device is put into use, soil material needs to be prepared in advance in the seedling cultivation trays or buckets. Once formed, the soil is transported as a whole, and then cotton seedlings are added in one batch. However, in this process, the soil in some cultivation buckets may be too loose or compacted. Furthermore, the amount of seedlings added is difficult to control, leading to uneven sowing and unreasonable density, both of which affect the normal growth level of cotton seedlings or result in inconsistent seedling survival rates. Additionally, the amount of soil covering the cotton seedlings is difficult to control. Too little soil leaves the seeds exposed, making them susceptible to environmental influences and reducing germination and survival rates; too much soil can smother the seeds, affecting germination and reducing the overall effectiveness and quality of cotton seedling cultivation.

[0004] Therefore, those skilled in the art have provided a disease and pest resistant cotton seedling cultivation device to solve the problems mentioned in the background section. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a disease and pest-resistant cotton seedling cultivation device, which solves the following problems: In the use of existing disease and pest-resistant cotton seedling cultivation devices, it is usually necessary to prepare soil material in seedling cultivation trays or buckets in advance after the seedling cultivation device is put into use. After the soil material is formed, it is transported as a whole, and then cotton seedlings are added as a whole. However, in this process, the soil in some cultivation buckets is too loose or hard, and the amount of seedlings added cannot be controlled. This leads to uneven sowing and unreasonable density, which will affect the normal growth level of cotton seedling cultivation or cause inconsistent seedling survival rates. In addition, it is difficult to control the amount of soil covering during the cotton seedling cultivation process. Too little soil will expose the seeds, making them susceptible to environmental influences and reducing the germination rate and survival rate. Too much soil will cause the seeds to be pressed down, affecting seed emergence and reducing the overall cotton seedling cultivation effect and quality.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0017] The beneficial effects of this invention are:

[0018] 1. The disease and pest prevention cotton seedling cultivation device of the present invention drives the top ring frame to move through the main control component. After descending to a predetermined height, it abuts against the positioning pressure rod, causing the positioning pressure rod to slide between two limiting blocks. Under the push of the positioning pressure rod, the first top block slides in the spring telescopic frame. After sliding to a predetermined distance, it pushes the second top block to slide in the spring telescopic frame, further driving the L-shaped linkage rod to move. Under the movement of the L-shaped linkage rod, it drives the two unfolding rods to move. Under the movement of the unfolding rods, it pulls the two arc-shaped fixed rods to rotate on the limiting pin seat. When the arc-shaped fixed rods move, they drive the small gear to roll along the arc-shaped toothed rod, thereby driving the two bottom plates to rotate synchronously when expanding outward. When the predetermined compaction is reached, the bottom plates open, and the cultivated soil base column is formed and brought into the cultivation trough. This is beneficial for the rapid formation of the seedling soil layer for cotton seedlings, preventing the cultivation soil from being loose or hardened, avoiding the dispersion of seedlings, and ensuring the survival rate of the cultivation.

[0019] 2. The disease and pest prevention cotton seedling cultivation device of the present invention, after the L-shaped pusher is pushed by the extended end of the first electric push rod, causes the limiting push plate to move sequentially and push the cultivation soil base column into the cultivation trough. When it is about to reach the predetermined position, the micro telescopic device extends and drives the combing mesh plate to move, causing the baffle plate to slide in the quantitative conveying box, releasing the soil that has entered the soil covering pipe from the soil conveying hopper and then slid into the quantitative conveying box, thereby quantitatively covering the cultivation soil base column with seedlings. When the micro telescopic device retracts, it can drive the combing mesh again. The plate transports the soil for covering the seedlings. Simultaneously, as the soil is covered for the next seedling base column, the movement of the entire quantitative conveying box allows the combing mesh plate to loosen the soil from the previous covering. When one of the cultivation troughs is full, the servo motor drives the threaded rod to rotate, causing the threaded sleeve block to slide on the U-shaped through-hole frame. During the sliding, the guide slide moves as a whole, thereby adjusting the pushing position of the limiting push plate. This allows the device to automatically cover the seedlings with soil after planting, regularly loosen the soil, prevent uneven soil covering, and improve the overall seedling cultivation efficiency and quality.

[0020] 3. The disease and pest prevention cotton seedling cultivation device of the present invention, when the bottom plate is opened, drives the linkage rotating frame to rotate outside the cultivation soil forming sleeve. After the linkage rotating frame rotates, it drives the arc-shaped rack to move, so that the toothed movement causes the fan-shaped rack to rotate counterclockwise within the fixed mounting frame. After the fan-shaped rack rotates, it can pull the linkage plate down, causing the traction rod to slide in the first sleeve. When the first sleeve slides, it drives the pressure plate to compress the reset spring, thereby pulling the feeding plate to slide in the limiting channel under the movement of the traction rod. This allows a certain amount of cotton seedlings to enter the limiting channel and slide down along the seedling guide tube onto the cultivation soil base column. Then, when the seedlings are transported to the predetermined position by the conveyor belt, it is beneficial to control the amount of cotton seedlings cultivated, prevent the seedlings from being scattered, and improve uniformity.

[0032] This invention provides a disease and pest-resistant cotton seedling cultivation device, which solves the following problems: In the use of existing disease and pest-resistant cotton seedling cultivation devices, after the seedling cultivation device is put into use, it is usually necessary to prepare soil material in seedling cultivation trays or buckets in advance, transport it as a whole after it is formed, and then put cotton seedlings in one batch. However, in this process, the soil in some cultivation buckets is too loose or hard, and the amount of seedlings put in cannot be controlled. Uneven sowing and unreasonable density will occur when sowing the seedlings, which will affect the normal growth level of cotton seedling cultivation or lead to inconsistent seedling survival rates. Moreover, it is difficult to control the amount of soil covering during the cotton seedling cultivation process. Too little soil will expose the seeds, making them susceptible to environmental influences and reducing the germination rate and survival rate. Too much soil will cause the seeds to be pressed down, affecting seed emergence and reducing the overall cotton seedling cultivation effect and quality.

[0033] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0034] like Figures 1-9As shown, the pest and disease resistant cotton seedling cultivation device of the present invention includes a multi-functional seedling cultivation box 1.

An observation window 2 is provided at the front end of the multi-functional seedling cultivation box 1. A cotton seedling feeding hopper 4 and a soil conveying hopper 6 are respectively inserted and installed at the upper end of the interior of the multi-functional seedling cultivation box 1. A conveyor belt 13 is installed at the bottom end of the interior of the multi-functional seedling cultivation box 1. A cultivation soil base column 23 is provided at the upper end of the conveyor belt 13. A plurality of cultivation troughs 15 are provided at the bottom end of the interior of the multi-functional seedling cultivation box 1, and the cultivation troughs 15 correspond to the conveyor belt 13. A spring telescopic frame 39 is fixedly connected inside the multi-functional seedling cultivation box 1. The inner wall of the multi-functional seedling cultivation box 1 is fixedly connected to the spring telescopic frame 39. The multi-functional seedling cultivation box 1 is equipped with a main control component 551. The main control component 551 includes a main hydraulic push rod 33 fixedly installed on the upper wall inside the multi-functional seedling cultivation box 1. A top ring frame 22 is fixedly connected to the extended end of the main hydraulic push rod 33. A forming plate 16 is inserted and installed in the middle of the top ring frame 22. An open hemisphere 46 is provided at the bottom of the forming plate 16. A negative pressure spring 35 is fitted on the outer surface of the forming plate 16. A soil forming sleeve 10 that works with the forming plate 16 is fixedly connected to one end of the spring telescopic frame 39. A positioning plate 42 is fixedly connected to the bottom of the cotton seedling feed hopper 4. Two seedling guide tubes 17 are fixedly connected to the bottom of the positioning plate 42. Both seedling guide tubes 17 work with the soil base column 23. Soil conveying hopper A soil covering conveying assembly 553 is inserted at the bottom of the soil conveying hopper 6. The soil covering conveying assembly 553 includes a soil covering distribution pipe 18 inserted at the bottom of the soil conveying hopper 6. A quantitative conveying box 20 is fixedly connected to the bottom of the soil covering distribution pipe 18. A micro telescopic device 26 is fixedly connected to one side of the quantitative conveying box 20. A baffle plate 25 is slidably arranged inside the quantitative conveying box 20. A combing mesh plate 27 is fixedly connected to the extended end of the micro telescopic device 26. The baffle plate 25 and the combing mesh plate 27 are fixedly connected. A displacement auxiliary assembly 556 is provided inside the multifunctional seedling cultivation box 1. A fixed mounting frame 8 is fixedly connected inside the multifunctional seedling cultivation box 1. An auxiliary seedling placement assembly 552 is rotatably installed at the bottom of the fixed mounting frame 8. One end of the soil conveying hopper 6 is fixedly connected to The system includes a molding and cultivation component 554, a linkage feeding component 555 slidably mounted on the inner side of a spring telescopic frame 39, a limiting material channel 59 on the inner side of a positioning plate 42, a soil conveying channel 11 obliquely mounted between a soil conveying hopper 6 and a soil molding sleeve 10, a baffle 62 slidably mounted on the side of the soil conveying channel 11 near the soil conveying hopper 6, a lifting frame 19 fixedly connected to one side of a top ring frame 22 for use with the baffle 62, a linkage feeding component 555 including a first top block 37 and a second top block 38 slidably mounted on the inner side of the spring telescopic frame 39, an L-shaped linkage rod 40 vertically fixedly connected to the middle of the second top block 38, and a transfer and release component 557 at the lower part of the soil molding sleeve 10.Two limiting blocks 34 are provided on the outer surface of the top ring frame 22. A positioning pressure rod 36 is rotatably connected to the upper end of the first top block 37. The two limiting blocks 34 cooperate with the positioning pressure rod 36. The transfer and release assembly 557 includes a limiting pin seat 64 fixedly connected to the outer surface of the soil molding sleeve 10. Two bottom plates 47 are provided at the bottom end of the soil molding sleeve 10. Arc-shaped fixed rods 49 are fixedly connected to the outer surfaces of both bottom plates 47. A small gear 50 is fixedly fitted on one side of each of the two arc-shaped fixed rods 49. Both arc-shaped fixed rods 49 are rotatably connected to the limiting pin seat 64. Arc-shaped gear rods 63 that mesh with the small gear 50 are fixedly connected to both sides of the limiting pin seat 64. An unfolding rod 48 is rotatably connected between the L-shaped linkage rod 40 and the two arc-shaped fixed rods 49.

[0035] The above technical solution involves opening the automatic controller 3 to feed cotton seedlings and soil for seedling cultivation from the cotton seedling feed hopper 4 and soil conveying hopper 6, respectively. After entering the soil conveying hopper 6, the soil then flows into the soil conveying channel 11 and the covering distribution pipe 18. Soil in the soil conveying channel 11 slides into the soil forming sleeve 10. When the main hydraulic push rod 33 is opened and operates, it pushes the top ring frame 22 to descend vertically, thereby causing the lifting frame 19 to descend. Without the support of the lifting frame 19, the baffle 62 automatically falls to intercept the soil conveying through the soil conveying channel 11, thus completing the quantitative addition of soil. The top ring frame 22 then continues to descend, compressing the negative pressure spring 35, causing the forming disc 16 and the perforated hemisphere 46 to press against the soil base column 23. Simultaneously, as the top ring frame 22 moves, it descends to a predetermined height and abuts against the positioning pressure rod 36, causing... The positioning pressure rod 36 slides between the two limiting blocks 34. Under the push of the positioning pressure rod 36, the first top block 37 slides in the spring telescopic frame 39. After sliding to a predetermined distance, it pushes the second top block 38 to slide in the spring telescopic frame 39, further driving the L-shaped linkage rod 40 to move. Under the movement of the L-shaped linkage rod 40, it drives the two unfolding rods 48 to move. Under the movement of the unfolding rods 48, it pulls the two arc-shaped fixed rods 49 to rotate on the limiting pin seat 64. When the arc-shaped fixed rods 49 move, they drive the pinion 50 to roll along the arc-shaped toothed rod 63, thereby driving the two bottom plates 47 to rotate synchronously when expanding outward. When the predetermined compaction is reached, the soil base column 23 is brought into the cultivation trough 15 after it is formed, which is conducive to the rapid formation and quantity control of the seedling soil layer of cotton seedlings, preventing the cultivation soil from being loose or hardened, avoiding the dispersion of seedlings, improving uniformity, and ensuring the survival rate of cultivation.

[0036] A further technical solution includes an auxiliary seedling feeding component 552 comprising a fan-shaped toothed frame 14 rotatably mounted at the bottom of a fixed mounting frame 8, a linkage plate 45 rotatably connected to one side of the fan-shaped toothed frame 14, and several teeth on one side of the fan-shaped toothed frame 14. A linkage rotating frame 61 is rotatably connected to the outer surface of the soil forming sleeve 10, and an arc-shaped toothed rack 9 is rotatably connected to the bottom of the linkage rotating frame 61. The arc-shaped toothed rack 9 meshes with the teeth. A first sleeve 7 is obliquely mounted on the inner side of the fixed mounting frame 8. A traction rod 44 is movably inserted in the middle of the first sleeve 7. A pressure plate 41 is welded to one side of the traction rod 44 inside the first sleeve 7. A reset spring 43 that works with the pressure plate 41 is provided inside the first sleeve 7. The traction rod 44 is rotatably connected to the linkage plate 45. A feeding plate 58 is connected to the bottom of the traction rod 44. The feeding plate 58 is movably inserted into the limiting channel 59.

[0037] The above-mentioned technical solution involves the bottom plate 47 driving the linkage rotating frame 61 to rotate outside the soil forming sleeve 10 when it is opened. After the linkage rotating frame 61 rotates, it drives the arc-shaped rack 9 to move, causing the toothed frame 14 to rotate counterclockwise within the fixed mounting frame 8. After the fan-shaped rack 14 rotates, it can pull the linkage plate 45 down, causing the traction rod 44 to slide in the first sleeve 7. When the first sleeve 7 slides, it drives the pressure plate 41 to compress the reset spring 43, thereby pulling the feeding plate 58 to slide in the limiting channel 59 under the movement of the traction rod 44. This allows a certain amount of cotton seedlings to enter the limiting channel 59 and slide down the seedling guide tube 17 onto the soil base column 23. Then, when the seedlings are transported to the predetermined position by the conveyor belt 13, it is beneficial to control the number of seedlings and automatically release the seedlings during the operation of the device, thereby improving the sowing efficiency and quality before cultivation.

[0038] A further technical solution includes a displacement auxiliary component 556 comprising a U-shaped port frame 24 fixedly connected to the bottom wall inside the multi-functional seedling cultivation box 1. A threaded rod 66 is rotatably mounted on the inner side of the U-shaped port frame 24. A servo motor 12 is mounted on one side of the U-shaped port frame 24. The output shaft of the servo motor 12 is fixedly connected to the U-shaped port frame 24. A threaded sleeve block 32 is threadedly fitted on the outer surface of the threaded rod 66. The threaded sleeve block 32 is slidably disposed with the U-shaped port frame 24. A guide slide 31 is slidably disposed on the upper surface of the U-shaped port frame 24. The guide slide 31 is fixedly connected to the threaded sleeve block 32. A custom frame 21 is slidably disposed on the inner side of the guide slide 31. A first electric push rod 30 is inserted and fixedly installed in the middle of the custom frame 21. An L-shaped push frame 28 is fixedly connected to one end of the first electric push rod 30. A limiting push plate 29 is disposed on the inner side of the L-shaped push frame 28. A quantitative conveying box 20 is fixedly connected to the L-shaped push frame 28.

[0039] The above technical solution involves using the extended end of the first electric push rod 30 to push the L-shaped pusher 28, causing the limiting push plate 29 to move and sequentially push the soil base column 23 into the cultivation trough 15. When it is about to reach the predetermined position, the micro telescopic device 26 extends and drives the combing mesh plate 27 to move, causing the baffle plate 25 to slide in the quantitative conveying box 20. This releases the soil that has entered the soil covering pipe 18 from the soil conveying hopper 6 and then slid into the quantitative conveying box 20, thereby quantitatively covering the soil base column 23 with seedlings. When the micro telescopic device 26 retracts, it can drive the combing mesh plate 27 to cover the soil. The soil is transported, and when the next soil base column 23 is covered with soil, the movement of the entire quantitative conveying box 20 allows the combing mesh plate 27 to loosen the soil covered by the previous soil again. When one of the cultivation troughs 15 is full, the servo motor 12 drives the threaded rod 66 to rotate, causing the threaded sleeve block 32 to slide on the U-shaped through frame 24. When sliding, it drives the guide slide 31 to move as a whole, thereby adjusting the pushing position of the limiting push plate 29. This is beneficial for the device to automatically cover the soil after the seedlings are planted, and can regularly loosen the soil to prevent uneven soil covering, thereby improving the overall seedling cultivation efficiency and quality.

[0040] This invention also provides a disease and pest resistant cotton seedling cultivation device, the specific working principle of which includes the following steps:

[0041] When using this cultivation device, by turning on the automatic controller 3, cotton seedlings and soil for seedling cultivation are fed into the cotton seedling feed hopper 4 and soil conveying hopper 6, respectively. After the soil enters the soil conveying hopper 6, it enters the soil conveying channel 11 and the soil covering distribution pipe 18. The soil in the soil conveying channel 11 slides into the cultivation soil forming sleeve 10. When the main hydraulic push rod 33 is opened and operates, it pushes the top ring frame 22 to descend vertically, thereby driving the lifting frame 19 to descend. The baffle frame 62 automatically falls down without the support of the lifting frame 19, blocking the soil conveying in the soil conveying channel 11, thus completing the quantitative addition of soil. Then, the top ring frame 22 continues to descend, compressing the negative pressure spring 35, thereby allowing the forming... The disc 16 and the perforated hemisphere 46 press the soil-cultivating column 23. Simultaneously, as the top ring frame 22 moves, it descends to a predetermined height and contacts the positioning rod 36, causing the positioning rod 36 to slide between the two limiting blocks 34. Pushed by the positioning rod 36, the first top block 37 slides within the spring telescopic frame 39. After sliding a predetermined distance, it pushes the second top block 38 to slide within the spring telescopic frame 39, further driving the L-shaped linkage rod 40 to move. The movement of the L-shaped linkage rod 40 then drives the two unfolding rods 48 to move. The movement of the unfolding rods 48 pulls the two arc-shaped fixed rods 49 to rotate on the limiting pin seat 64. When the arc-shaped fixed rods 49 move, they drive the pinion 50 to roll along the arc-shaped gear 63, thereby causing the two bottom plates 47 to expand outwards. The components can rotate synchronously. When the desired compactness is achieved, the bottom plate 47 opens, and the formed soil column 23 is carried into the cultivation tank 15. Furthermore, when the bottom plate 47 opens, it drives the linkage rotating frame 61 to rotate outside the soil forming sleeve 10. After the linkage rotating frame 61 rotates, it drives the arc-shaped rack 9 to move, causing the teeth to move and the fan-shaped gear frame 14 to rotate counterclockwise within the fixed mounting frame 8. After the fan-shaped gear frame 14 rotates, it can pull the linkage plate 45 down, causing the traction rod 44 to slide in the first sleeve 7. When the first sleeve 7 slides, it drives the pressure plate 41 to compress the return spring 43, thereby pulling the feeding plate 58 to slide in the limiting channel 59 under the movement of the traction rod 44, thus allowing a certain amount of cotton seedlings to enter the limiting channel. Inside channel 59, the seedlings slide down the seed tube 17 onto the soil base column 23. Then, when conveyed to the predetermined position by conveyor belt 13, the extended end of the first electric push rod 30 pushes the L-shaped pusher 28, causing the limiting push plate 29 to move and sequentially push the soil base column 23 into the cultivation trough 15. When it is almost at the predetermined position, the micro-expansion joint 26 extends, driving the combing mesh plate 27 to move, causing the baffle plate 25 to slide within the quantitative conveying box 20. This releases the soil that previously entered the covering distribution pipe 18 from the soil conveying hopper 6 and then slid into the quantitative conveying box 20, thus quantitatively covering the seedling-sown soil base column 23 with soil. When the micro-expansion joint 26 retracts, it can again drive the combing mesh plate 27 to convey the covering soil.Simultaneously, when covering the next soil column 23 with soil, the movement of the entire quantitative conveying box 20 allows the sorting mesh plate 27 to loosen the soil from the previous covering again. Once one of the cultivation troughs 15 is full, the servo motor 12 rotates, driving the threaded rod 66 to rotate, causing the threaded sleeve block 32 to slide on the U-shaped through-hole frame 24. This sliding motion drives the guide slide 31 to move as a whole, thereby adjusting the pushing position of the limiting pusher 29. The overall situation inside the multi-functional seedling cultivation box 1 can be observed through the observation window 2. Once the overall seedling operation is complete, the process is finished.
